Your HVAC system works hard year-round to keep your home or business comfortable.
But like any mechanical system, it has a shelf life. Knowing when it’s time to update isn’t just about avoiding breakdowns—it’s about saving money, improving efficiency, and keeping your space safe and comfortable.

Here’s when you should give JBL Mechanical a call to discuss an HVAC system upgrade:
1. Your System Is 10+ Years Old
Most heating and cooling systems have a lifespan of 10 to 15 years. If yours is pushing or past that mark, it’s likely running less efficiently—and more expensively—than newer models. Upgrading can lower your energy bills and reduce the risk of unexpected failures.
2. You're Paying for Frequent Repairs
If you’ve called for HVAC repairs more than once or twice in the past year, your system is costing more than it’s worth. Investing in a new, reliable unit saves money and eliminates the stress of surprise breakdowns.
3. Uneven Heating or Cooling
Hot and cold spots in your home or office are a red flag. They often indicate airflow problems, aging ductwork, or a system that’s too small—or too old—to do the job properly.
4. Your Energy Bills Are Creeping Up
A spike in energy costs with no change in usage is a common sign your system is losing efficiency. Today’s HVAC units are significantly more energy-efficient, helping you save every month.
5. It Still Uses R-22 Freon
If your system uses outdated refrigerant like R-22, it’s not just inefficient—it’s also becoming impossible to service. Modern systems use safer, EPA-approved refrigerants that are better for your wallet and the environment.
6. You’re Remodeling or Expanding
Adding rooms or finishing a basement? Your current HVAC system may not have the capacity to properly heat or cool the added space. An upgrade ensures comfort throughout your entire home or business.
